An Annotated List of the Spiders of Indiana 1 Thomas A. Parker, Purdue University Introduction The history of Indiana araneology began in 1847 when Nicholas Marcellus Hentz, the Father of American Araneology, described A galena naevia from Indianapolis (29). Since that time many have contributed to the list of spiders of Indiana. Notable among these contributions are the works of Fox (25), Banks (2), and Elliott (20, 21, 22). Dr. William H. Fox published the first list of Indiana spiders (25), which was based on a collection of a chemistry professor at Purdue Uni- versity, Mr. Frederick C. Test. This list included 79 species of spiders in what would today be 16 families, although family names were not used in this list. Nathan Banks published a preliminary list of Indiana spiders in 1907 (2). This work included keys to the families and genera of spiders and, in addition, a list of species belonging to other arachnid orders. The list of spiders included 148 species found in 16 families, two species of which were described as new to science. The list was based on spiders collected by W. S. Blatchley, Mel T. Cook of Greencastle, W. J. Moenkhaus of Huntingburg, and A. M. Banta who collected spiders in Indiana caves. In 1930 the late Dr. Frank R. Elliott published on spiders of a beech- maple forest near Richmond, Indiana (20). Combining the records of Banks with newly collected material and his beech-maple study, Elliott published a list of Indiana spiders in 1932 (21). This list contained 218 species of spiders found in 20 families. Elliott again published a list of Indiana spiders in 1953 (22). It was based on records in the literature and newly collected material. The work of Lowrie (38, 39) on the spiders of the Chicago area dunes greatly con- tributed to the records of Indiana spiders. Using these records and others, Elliott assembled a list containing 303 species of spiders found in 21 families. No major studies of the spiders of Indiana have been published since Elliott's 1953 list. This paper, then, will enlarge, correct, and update the list of Indiana spiders. The List The present list of Indiana spiders contains 378 species of spiders found in 29 families. The families are arranged following the system used by Kaston (32). The genera are alphabetically arranged in the families and likewise the species in the genera. Nomenclature generally follows 1 Journal Paper No. 3771, Purdue University Agricultural Experiment Station. 266 Entomology 267 that used by Kaston. Synonyms are included beneath the accepted scien- tific name in cases where name changes have occurred within the last twenty years. The species are numbered consecutively. Collection records are arranged by county with the oldest record pre- ceding all others. The counties are in bold-faced type. Usually the local- ity is given in parenthesis, followed by citations in which the record was found. In instances where no locality was given in the literature or where recent collectors gave no specific locality on their labels, just the citation or date collected and collector's initials are included in the parenthesis. If the record is a recent one, the collection dates and collector's initials are included. Names of collectors may be found in Appendix I. Many of the localities recorded in the older publications no longer exist, having been incorporated into neighboring cities. Other names appearing in the literature were local names and were not formally recog- nized. Appendix II enables the reader to locate such places more accu- rately. Also included in this appendix are a few localities visited by the author or his colleagues for which a more specific geographical description was deemed necessary. The writer's spider collection is housed in the Entomology Depart- ment at Purdue University. All identifications of recent collections were made by the writer. Some verifications were obtained from araneologists in the United States and Canada. Such determinations are credited to these men individually in the text. This list is based on records from the literature and the collection of the writer. This collection represents spi- ders collected during a three-year study of spiders along the Wabash and Tippecanoe Rivers, spiders sent for determination through the Cooperative Extension Service, and specimens collected by students and staff of the Entomology Department at Purdue University. ORDER Araneida Suborder Orthognatha family Atypidae 1. Atypus milberti (Walckenaer), 1837 Crawford (Wyandotte Cave, Sept. 8, 2, 21, 22); Posey (New Harmony, 2, 21, 22); INDIANA (49); Warren (South Pine Creek, May 5, 1968, GRF) family Ctenizidae 2. Aptostichus flavipes Petrunkevitch, 1925 Lawrence (Mitchell, 50, 51, 22) Petrunkevitch (51) reported this species in his Catalogue of American Spiders, Part 1, not in his synonymic index (49), as Elliott (22) has indicated. 3. Pachylomerides audouini (Lucas), 1836 Floyd (Floyd's Knobs, 45); Harrison (Corydon, May 12, 1968, CB) 268 Indiana Academy of Science The specimen from Harrison County was sent to the writer by Jack Washburn, County Agent. It was found in the driveway at the home of Cova Bates. Suborder Labidognatha family Dysderidae 4. Dysdera crocata C. L. Koch, 1839 Whitley (Columbia City, Aug. 28, 1967, RLG); Cass (Logans- port, Mar. 30,1967, TH) family Segestriidae 5.

U, 1967, TAP) ; Posey (Mount Vernon, Jan. 19, 1968, TAP; Poseyville, May 23, 1968, TAP); Clark (Jeffersonville, Mar. 28, 1968, TAP); Knox (Bruceville, Mar. 18, 1968, RED); Vanderburgh (Evansville, May 28, June 3, 1968, TAP); Dubois (Jasper, June 26,1968, DJM) family Pholcidae 8.

Conopistha rufa (Walckenaer), 1841 Argyrodes trigonum (Hentz), 1850 Monroe (Mayfield's Cave, 4, 22; Twin Cave, 4, 21) Entomology 269 The Twin Cave record of Banks is from a specimen sent to him by Banta and probably is Banta's "Lower Twin Cave at Mitchell" which is in Lawrence County. 12. Crustulina altera Gertsch & Archer, 1942 C. guttata: (Emerton), 1882 (nee Theridion guttatum Wider, 1834) Wayne (Richmond, 20, 21, 22, 39); Steuben (Crooked Lake, 21, 22); Porter (Valparaiso, 21, 22; Ogden Dunes, 39, 22); Tippe- canoe (Ross Biological Reserve, 5) Elliott (21, 22) listed Crustulina guttata (Wider). Willis J. Gertsch considers our species separate from the European guttata (Wider), hence the name altera. Kaston (32), page 75, says, "In general appearance and structure of the genitalia this species [C. altera] closely resembles gut- tata (Wider), with which, in fact, it may be identical, although Dr. Gertsch thinks not." 13. Ctenium pumilus (Emerton), 1909 Wayne (Richmond, 20, 21, 22) 14. Ctenium riparius (Keyserling), 1886 Knox (May 26, 2, 21, 22); INDIANA (49); Wayne (Richmond, 21, 22); Porter (Ogden Dunes, 39, 22) 15.

Latrodectus variolus Walckenaer, 1837 Putnam (Greencastle, 2, 21, 22, 42); Porter (Dunes Acres, 38, 39, 42; Ogden Dunes, 39, 42); Brown (Aug. 10, 1967, May 1, 1968, JJF) Levi (35) synonymized Latrodectus variolus with L. 7nactans. Actu- ally what is now known as L. variolus was included in Levi's records of L. curacaviensis. McCrone and Levi (42) showed that L. variolus is a valid species based on coloration and ecology. Therefore the records 270 Indiana Academy of Science listed for Latrodectus curacavie?isis for Indiana in Levi's paper are actually L. variolus and are herein listed as such. 20.
